Metallic taste | pregnancy symptoms| vent out

We have been TTC for 2 years, . I had 2 early miscarriage is the past. We are trying without losing hope keep other couples who are really struggling a lot more than us.

I have irregular periods and pcos. I'm currently taking levothyroxine and doc asked me to wait until next month for metphormin.

We had sex 2 weeks before and I have on and off nipple soreness and a wierd taste in my mouth. I couldn't wait and I took a test. It came negative. When to test if my longest period is 75 days . Feeling confused and depressed.

Thanks
